I don't know about all of that, but I do notice that the game has a catch-up spawn mechanic. If you're losing, the game will give you a more favorable spawn point. I take advantage of this sometimes in control when my team is losing. I'll save my super and allow the enemy to get a power play. Then the game gives us better spawns and we reverse the power play on them and win. One good sweep through the enemy team with a super or two usually seals the deal. If you ever have a match where the enemy team starts fighting back harder against you, this is usually why. The game will give them a better spawn. I've also figured out that the spawns will happen according to where your team is mostly located in the map. It will always spawn them the furthest from you. It only deviates sometimes, when the catch-up mechanic kicks in and will spawn one enemy in your spawn. That usually happens about twice a game in control.
